Timing is essential when it comes to removing your resin crystal from a silicone mould. Taking it out too soon or too late can affect the finish and ease of demoulding. Here’s what resin crafters need to know for best results.
How Long Should You Wait?
The key to a flawless mould release is letting your resin cure fully. Most clear casting resins advise a demoulding time between 12 and 24 hours, but it’s important to always follow the specific product instructions. If removed too early, the crystal may be soft or develop fingerprints. Waiting the recommended period ensures the piece is strong, glassy, and less prone to distortion.
Why Timing Matters for Clarity and Shape
Resin that isn’t cured enough can bend, smudge, or even stick to the mould, spoiling that coveted glass-like clarity. High-quality silicone moulds, like the Diamond Crystal Silicone Mould, are designed for easy demoulding once resin has set. If you’re working in a humid or cool environment, give your project extra time; coolness slows curing and may make your piece more prone to breakage if rushed.
Tips for Safe and Clean Demoulding
- Gently flex the mould to loosen edges and release the crystal.
- Avoid sharp or aggressive tools; silicone can tear.
- If there’s resistance after the recommended time, leave the piece an extra couple of hours.
- Choose resins formulated for clarity, like Icrystal Clear Epoxy, for the most striking results.
